What is view state management in ASP.NET MVC?

View state management in ASP.NET MVC refers to how the framework maintains the state of a web page across postbacks. Unlike Web Forms, MVC does not use view state by default, but you can implement state management techniques like TempData, ViewData, and Session.

Can you explain the differences between TempData, ViewData, and Session?

Sure! TempData is used to pass data between actions, ViewData is a dictionary for passing data to the view, and Session stores user data across multiple requests.

When should I use TempData instead of Session?

Use TempData when you need to pass data only for the next request, while Session is suitable for data that needs to persist across multiple requests.

Are there any performance considerations with using Session?

Yes, using Session can impact performance, especially if it stores large amounts of data or if the session state is stored in a database. It's important to manage session size and duration.
